On the Time Variable Rotation Measure in the Core Region of Markarian 421
In this conference contribution, we discuss and interpret the time variable rotation measure (RM) detected in the core region of the TeV blazar Markarian 421 (Mrk 421).

Chiral symmetry breaking and restoration by helical magnetic fields in AdS/CFT
We study the effects of helical magnetic fields on chiral symmetry breaking within the AdS/QCD framework using the D3/D7-brane model. By analyzing the brane embeddings, we obtain three types of massless solutions, corresponding to three phases with ...

Prediction of Axial Asymmetry in Jovian Magnetopause Reconnection
We show the possible existence of a significant axial asymmetry in the reconnection separator at the Jovian magnetopause using first‐principle, physics‐based global simulations. Under eastward interplanetary magnetic field (IMF) conditions near Jupiter's

Relative magnetic field line helicity [PDF]
Context. Magnetic helicity is an important quantity in studies of magnetized plasmas as it provides a measure of the geometrical complexity of the magnetic field in a given volume. A more detailed description of the spatial distribution of magnetic helicity is given by the field line helicity, which expresses the amount of helicity associated to ...

Theory of the Kinetic Helicity Effect on Turbulent Diffusion of Magnetic and Scalar Fields
Kinetic helicity is a fundamental characteristic of astrophysical turbulent flows. It is not only responsible for the generation of large-scale magnetic fields in the Sun, stars, and spiral galaxies, but it also affects turbulent diffusion, resulting in ...

Cosmological magnetic fields from primordial helicity
Primordial magnetic fields may account for all or part of the fields observed in galaxies. We consider the evolution of the magnetic fields created by pseudoscalar effects in the early universe. Such processes can create force-free fields of maximal helicity; we show that for such a field magnetic energy inverse cascades to larger scales than it would ...

Coherent Resonant Soft X-ray Scattering Study of Magnetic Textures in FeGe
Coherent resonant soft X-ray scattering was utilized to examine the magnetic textures in a thin plate of the cubic B20 compound FeGe. Small-angle scattering patterns were measured with controlled temperatures and magnetic fields exhibiting magnetic ...

LISA and γ-ray telescopes as multi-messenger probes of a first-order cosmological phase transition
Aims. We study two possible cosmological consequences of a first-order phase transition in the temperature range of 1 GeV to 103 TeV: the generation of a stochastic gravitational wave background (SGWB) within the sensitivity of the Laser Interferometer ...
